. PERPETUAL CALENDAR.

This invention relates to calendars and more particularly to types adapted to be disposed on desks and like flat surfaces in plain view of persons in the vicinity, such calendars being preferably combined with a base to be used as a paper weight, with or without a tray to contain miscellaneous small objects. 7 V

.In calendars of this type the year is seldom' shown, but the month, days of the week anddays of the month appear, the days of the week remaining fixed while the month and days thereof require adjustment at the beginningof each month to properly coordinate. I V

The present invention has-as its main object to provide a neat and attractively designed calendar frame appropriate as a desk ornament aside from the useful function of revealing the ordinary features of a common calendar.

Another purpose is in the provision of an easy and convenient means for shifting the scroll, bearing the numerals representing the days of the month, into proper relation to a fixed plate showing the names of the.

days of a week and having combined therewith efficient means for'clamping the scroll A further feature is to design a device that can be economically constructed from sheet metal, easily assembled and adjusted, and readily madeuseof as an advertising medium of unusual merit.

These several valuable features are attained by the ;novel construction andcombination of parts hereinafter described and shown in the annexed drawing, constituting an essential part of this disclosure, and in which Figure l is .a front elevational view of a perpetual calendar made in accordance with the invention.

Figure 2 is an end elevational view of the same.

Figure 9 s an enlarged fragmentary sectionalview taken on line 9-9 of Figure 1 showing the frame construction PATENT crime.

Figure 10 is a fragmentarysectional view taken on line 101 0 of Figure 8, showing the scroll gripping means. i

In the illustration the device is showni tol consist of a generally oblong rectangular base 15 artistically die formed :from sheet metal and having on its under side a sheet of felt.16 to avoid abrading the surface on which .it may be placed. l I

The front portion of the base may be depressed to constitute atray, not shown, and 1 on the rear portion is fixed a rearwardly inclined bracket 17 engaging the lower mem-v ber of a rectangular frame consisting .of a front plate 18 having rearwardly reaching flanges 19 at each of its four sides, these flanges extendingat rightangles and having inwardly offset perforations 21. g v v The front plate '18 may be fancifully borportions 20 containing small dered as shown and its lower portion 18 is adapted to receive any desired impression,

as an advertising device. A-raised panel 22 on the upper part of the plate contains an I elongated opening 23 throughwh-ich is disclosed a stripof material 24, such asopaque; .white celluloid, bearing printedwordsrep resenting the days of the week, as Sunday,

Monday, etc. p Q, I

Centrally above the opening 231 is a small opening 25 and in register below the opening 23 is a wider opening 26.; .a thin sheet 27of transparent material such as mica or celluloid is fitted to theframeand disposed against the inner surface of the plate 18, rearward of the strip 24 and covering the openings 25 and 26 preventing, the entrance ofqdirt to the interior. v

Rearward of the transparent sheet27 is a metal plate .28 ofslightly lesser dimensions and havingprojections 29 turned rearwardly at right angles at each corner, acting to maintain the plate at the front as willlater be seen.

A recess .30 extends downwardly from the upper edgeof the plate 28 correspondingtd the :opening25 in the face plate, and below' the recess is a tubular boss 31 on which is rotatably mounted a disc 32, such aswhite opaque-celluloid, bearing a circular row of spaced words designating the months of a year, as January, February, etc., the same showing through the recess: 30, transparentsheet 27 and opening 25,

'' Registering radially with the words is an inner circular -row of perforations 33,

equally spaced and equidistant from the center of the disc 32, which is held on'the boss 'by'spinning its tubular edge outwardly as best seen in Figure 4.

Engageable in any of the perforations 33 is a detent 34 formed near the end of a spring tongue 35 sheared from the material of the plate 28, this arrangement servingto 'retainjthe' disc in adjusted position to dis close any selected month at the front of the 20 calendar, but permitting the extending edge of tlie disc to be manipulated in turning in either direction.

The main portion of the lateral edges of the plate 28, between the projections 29,

are curved to present hollow smoothly rounded guides 36, disposed in parallel closely adjacent the side flanges 19 of the frame, theinner edges of the guides being "extended, inwardly towards the center.

"'Afscroll or-strip 37, made of strong flexible material, as enamel coated muslin, is provided with lines dividing its outer surface into a plurality of squares .on which are shown five rows of numerals, each row containing numerals arranged to agree w th. r

, the days of the month this scroll extending interjacent the plate 28 and transparent 7 their. central portions sheet 27 and over the guides 36 todisclose 4 the numerals through the opening 26.

pairs of perforations 40 and the opposite sides are formed with spurs 41 which en.- gage the fabric scroll ends and, iii connec- -tion withtheperforations 40, hold them in L firm'engagement when'the clamp .members are pinched together, asbest seen in Figure 10f 1 v r v A rear, or cover plate 42 is formed with edge flanges 43 suited to engage neatly over the flange elements 20 of the front plate, the side flanges 'of the. rear plate having inset prongs 44 to engage in the'perforations 21' holding the structure firmly together.

a A. transverse slot 45is formed centrally acrossnearly the entire width ofqthe rear. plate and guided by the slot is a slide 46 -ofii'set from a plate 47 having at its ends,

i opposed lugs 48 adapted to extend past the edges of the paired clamps 38, closely against their shoulders and be turned thereover, as best seen inl igure 8, binding the scroll carrying clamps and slidefirmly together.

Fixed in the center of the slide 46 is a stem 49 formed on one side of a collar 50 disposed on the outer surface of the rear plate 42 and having an outwardly extending screw 7 threaded stem 51 to'which is fitted a thumb nut 52.

The nut 52 seats against a hollow washer 53 which upon setting up the nutbinds the slide in adjusted position and, as will be clearly apparent, maintains the scroll in proper relation with the strip 24, in' con-1 formity with a standard calendar; it will be noted that the collar 50 retains the slide within the slot at all tiines,"irrespective of the nut, thus'preventing disarrangement of the parts. I r

7 It will now be apparent that the months may be changed by actuating the disc32,

and the first day of any month be brought to register with the proper day of the week by actuating the knob or nut 52, such changes being required at the beginning of each month only. a

Although I have merit, iithconsiderable detail and with respect to certain particular forms of my invention, I 'do not desire to be limited to such details since many changes and modifications may be made without departing from the spirit andyscope of my invention 1n its broadest aspect.

Having thus descr1bed my invention,what' I claim as new and desire to secure by Letters Patent, is I r i 1. In a perpetual calendar, a casing havdescribed my improve.

from the front wall bearing the days of the week, a scroll bearing the days of the month adjust-able across an opening in the front o wall, a" guide for said scroll, means for actuating the scroll, a tubular boss on said guide, a disc rotatablymounted on saidboss, said disc bearing the names of the months'to ap pear through arecess in said front plate;

the upper edge of said disc extending through the top of said casing to facilitate rotation, said disc having perforat1ons,cor-

responding to the names borne thereby, a spring tongue sheared fromjsaid gulde, and

a detent onsaid tongueengageable in any of the mentioned perforations whereby said discis held in adjustment. i
